In practice I prefer to make within the Similar letters refer to similar parts wherguide-block B a stea1n-jacket B which may ever they occur on the different parts of the be supplied with steam under pressure from drawings. a pipe 0, leading from a boiler or other source 5 In the drawings, A represents a suitable of steam-pressure. 5 table, bench, or support, on which is secured b b are steam ports or passages leading the driver or plunger guide-block B, which from the jacket or steam-chamberB to the receives the wood 0 to be twisted, as well as guide groove or perforation B, in which the the reciprocating driver or plunger D, as wooden bar C is being guided during the 50 shown in Figs. 1 and 2. The driver or pluntwisting operation, and by such arrangement I00 the wooden blank or bar is steamed and rendered more plastic and yielding during the twisting operation.

In alinement with the longitudinal perforation B of the guide-block B is arranged the twister-die F, which is detachably secured in a suitable manner to the support or table A, as shown. Said twister-die is provided with a longitudinal twisted bore or perforation f,

into which the green or steamed rod 0 is remain within the said twister-die until it is thoroughly dry, when it is removed from within said die. During such drying process I prefer to remove the said twister-die and the twisted rod remaining within it from the table A and replace it by another similar diefor twisting another rod, and so on.

To remove the twisted rod from within the twister-die F after said rod is dried and hardened, it is only necessary to push it out lengthwise therefrom either by means of the plunger D and a wooden rod placed in the guide-block B, by which the finished rod is being forced out of the die F during the twisting operation of the next rod, and so on; or, if so desired, the die F may be made in parts and divided longitudinally, as represented by dotted lines f f in Fig. 4, so as to enable such parts to be detached whenever it is desired to remove the twisted and dried wooden bar from within said twister-die.

In shaping the wooden bars or rods I proceed as follows: I take a wooden bar of any desired section, either green or steamed, and place it in the longitudinal groove B of the guide-block B and close the cover on said guide-block, afterwhich the said wooden rod is forced onward through said guide-block by means of the plunger D, causing the wooden bar to be forced into the torsionallytwisted perforation f in the twister-die F, by which the rod is made to assume the torsional form, as shown in Fig. 8, corresponding to the said torsional perforation f in the twister-die.

In the drawings I have shown said twisterdie as being straight for making straight rods; but said twister-die may be made segmental or curved in any suitable manner if it is desired to produce twisted as well as curved rods.

I wish to say that although a guide-block .is shown in the drawings and a reciprocating plunger or driver actuated by a rack and pinion such devices are not absolutely necessary, as the wooden rod may be forced through the twister-die in any other suitable manner without departing from the spirit of my invention.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim 1. A machine for imparting a torsional twist to wooden bars or rods having an angular shape in cross-section, consisting of a twister-die having a longitudinal bore of angular' shape in cross section, the walls of which are twisted torsionally along their length, and means for guiding and forcing the bars or rods to be shaped into said twisterdie, said guiding means being arranged to hold one end of the said rod or bar against rotation while being forced into the said twister-die.

2. A machine for imparting a torsional twist to wooden bars or rods having a polygonal shape in cross-section, said machine consisting of a twister-die having a longitudinal bore of uniform diameter throughout its length and of polygonal shape in cross-section, the inner walls of said bore being twisted torsionally along their length, and means for guiding and forcing the rods or bars to be shaped into said twister-die, said guiding means being arranged to hold one end of the bar or rod against rotation while being forced into the twister-die.

3. A machine for imparting a torsional twist to wooden bars or rods having an angular shape in cross-section, consisting of a 10n= gitudinally-grooved guide-block, said groove being of angular shape in cross-section and having a hinged cover by which access may be had to said groove, said guide-block being adapted to hold the rods or bars against rotation, a twister-die having a longitudinal bore of angular shape in cross-section, the inner walls of said bore being twisted torsionally along their length, and a driver or plunger for forcing the bars or rods to be shaped through the said guide-block and into the twister-die. 4. The herein-described machine for shaping wooden rods or bars, consisting of a twister-die having a 1011gitudinally-twisted bore through which the green or steamed wooden bar is forced and in which it is allowed to remain until it retains its twisted form and means for holding one end of the bar or rod against rotation while it is being forced into the twister-die, substantially as and for the purpose set forth.

5. The herein-described machine for shaping wooden rods or bars, consisting in combination a longitudinally grooved or perforated guide-block, said groove being angular in cross-section, and adapted to hold one end of thebar or rod against rotation, a twisterdie having a longitudinal twisted bore or perforation in alinement with the guide-groove in the guide-block, and a reciprocating driver or plunger for forcing the green or steamed bar through the guide-block and twisted bore the guide-groove and through the twisted bore or perforation in the twister-die, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, on this 26th day of March, A. D. 1897.
